VT999 : Oddity

I still have not got to grips with this unit. Initially unhappy with the sound I changed the valve for a youtube recommended one (plenty of alternatives going on there). The sound improved but the volume at 10 was lower than when the unit was off so I put in the original which equals the off volume at around no 7. With bass at almost max, mid 50% and treb down, gain at 4 the sound gets a bit like late 60s but needs some delay to fatten it up. I can't use it with wah unless the end of night tune demands a complete freak out. I have become attached to this unit but a bit like a family member I love but always get totally pissed with when we meet up, I may have to avoid it soon. Any suggestions for something smaller and more manageable would be appreciated.
